Attention deficit hyperactivity disorder is a series of behavioral symptoms including inattention, hyperactivity, and impulsiveness. ADHD symptoms tend to be identified at an early age and can become more noticeable when a child is goiong through a change in circumstances, for example, as they start kindergarten. Many reports suggest that the children most affected are between the ages of 6 and 12. Usually, symptoms of ADHD rise with maturity, although sometimes individuals dealing with the condition at a young age experience trouble as well. People with ADHD may have other difficulties as well, such as sleep disorders and anxiety. The precise cause of ADHD remains unknown however research on ADHD continue to date. Various studies have identified several possible differences in the minds of people with ADHD as opposed to those without the condition. Other factors suggested as having a potential role in ADHD include early birth, low birth weight, malnutrition, alcohol or drug abuse during pregnancy. ADHD is more prevalent in boys than in girls. The condition is estimated to be around 2 percent to 5 percent of school-age adolescents. ADHD may appear in individuals of any mental ability, but it is more common in individuals with cognitive impairments. While there is no cure for ADHD, it should, where necessary, be handled by medications and enough educational support, counseling and motivation for parents and children impacted. Medication is frequently the first form of treatment offered to individuals with ADHD, while psychological therapies such as cognitive behavioral therapy may also be of assistance. Treatment for a child with ADHD may be complicated, but it is important to remember that they can not alter their behavior. Many issues that can arise in daily life include getting the child to sleep at night, getting them up on time for school, listening to and following instructions, being organized and handling social events. Shopping with ADHD adults may also show that they have similar difficulties, while some may have problems with alcohol, abuse, and unemployment. Signs of attention deficit hyperactivity disorder can be split into two types of behavioral disorders. These forms include inattention, hyperactivity, and impulsiveness, but most people with ADHD do not usually have that. Any individuals with the condition can have trouble with inattention, but not hyperactivity or impulsiveness. ADD can even go ignored because the symptoms can be less visible. The precise nature of the diagnosis of attention deficit hyperactivity disorder is not widely established as it is thought to be responsible for a variety of reasons. ADHD tends to manifest across households, and in most instances, the genes you get from the parents are deemed a significant factor in the development of the condition. Data shows that all parents and friends of a child of ADHD are four or five times more likely to experience ADHD themselves. The cause of ADHD is complex, however, and is not believed to be linked to a common genetic mutation. Research has described several possible differences in the brains of those with ADHD compared to those who may not have the condition, but it is not clear what their exact definition is. For example, studies including brain imaging have found that certain areas of people with ADHD's brain can be smaller and other sections could be larger. Research has also shown that the brain may take an average of two to three years longer to grow in children with ADHD, compared to children without the condition. Some studies have indicated that people with ADHD might have a problem in the number of neurotransmitters in the brain, or do not work adequately with these chemicals. If you believe you or your child might have a diagnosis of hyperactivity or lack of focus, it is recommended that you speak to your doctor about this. If you are worried about your child, it might be useful to speak to their teachers before you see your doctor, to find out if they have any concerns regarding your child's behavior.
